To all whom it may concern.-

Be it known that I, JOHN SMITH, formerly of lWlarton, in the colony ofNew Zealand, but now residing at Melbourne, in the colony of Victoria,have invented a new and useful Composition for Waterproofing TextileFabrics or for a Paint for \Vood and other Surfaces, (for which I havereceived Letters Patent in the following countries: In England,No.10,858, dated July 5, 1889; in Victoria, No. 5,835, dated on or aboutthe 19th day of May, 1888; in New South ales, No. 1,441, dated May 27,1889; in South Australia, No. 1,310, dated May 28, 1889; in Queensland,No. 759, dated September 18, 1889, and in New Zealand, No. 3,749,datedJune 21, 1889,) of which the following is a specification.

This invention relates to a new composition for making textile fabricswater-proof, and to a certain extent fire-proof, being specially adaptedfor application to rugs, coats, and such coverings or articles ofapparel as are used for protect-ion against wet or damp. Thiscomposition is also applicable as a paint for wood, plaster walls, orany other surfaces requiring to be damp-proof or water-proof, and it isalso adapted for general purposes in which ordinary paint is used, andcan be applied with an ordinary paint-brush.

The novelty consists in the ingredients used in the manufacture, and theimproved result lies in the short time the composition takes to dry,beingfrom four to twenty-four hours, according to the purpose for whichit is used. A second coat can be put on, if desired; also, two coats ofthis paint are equal to three coats of ordinary paint, it lasts longer,and may be tinted to the required color.

In order that my invention may be easily understood,I will now describeits use. The composition may be equally well applied to the materialseither in the piece or made up. I treat the piece of fabric or articleof clothing with one coat of my composition; but I do not confine myselfto the application of one coat, as it will be found necessary in someinstances to apply two or more (one upon each side) in order to renderthe material thoroughly water-proof. To give a better finish to thematerial in the piece I pass the latter after, having immersed it in thecomposition, between two smooth-surfaced iron rollers arranged andrevolved in a manner similar to those in a calendering-machine. Thisinsures a more even surface to the piece of material and uniformthickness to the spread of the composition. I

Having now described the application of my invention to the variousmaterials and substances, I will give the component parts of thecomposition, which are as follows: ten hundred-weight of white lead, (Ifind best for the purpose is that known as Ohampionsg it should not betoo soft; that having a little age is best adapted;) sixty gallonslinseed-oil, (half of this quantity to be boiled, the other half rawthree hundred pounds(avoirdupois) of whiting entirely free from lumps;eightyeight pounds (avoirdupois) of sulphate of lime free of all grit;three pounds (avoirdupois) of crushed alum; forty pounds of glue (mediumquality;) fifty-six pounds of patent driers; fifty gallons of coldwater; one pound of marine blue to make the composition White.

The mode of combining and mixing the above ingredients is as follows:The linseedoil is first placed in an ordinary wooden vat. Then the whitelead is added (one hundredweight at a time.) The patent driers are nextintroduced. These ingredients are well mixed by means of an ordinarypaint-mixer or its equivalent. The whiting is placed separate in awoodenor iron vat (termed the whitingvat) and allowed to soak in sixteengallons of the Water taken from fifty gallons, before stated, for twelvehours, after which it is stirred to the consistency of a thick paste.The glue, alum, and seventeen gallons of the water are placed in anordinary copper boiler or vat and there allowed to remain for twelvehours. These quantities are then boiled and stirred until the glue isdissolved. The sulphate of lime is placed in another wooden or ironvessel, (arranged at one side of but higher than the whitingvessel,) andwell mixed with sixteen gallons of water and then added to and mixedwith the whiting and water before mentioned. To

this admixture the glue, water, and alum are added and blendedtherewith. The compound thus formed is let into the vat (through themedium of a tap or cock secured near the bottom of the whiting-vessel)containing the White lead, linseed-oil, and patent driers. The whole ofthe ingredients are then thoroughly blended by the paint-mixer or itsequivalent. The remaining one gallon of water is now used, or whateverquantity will make the mixture of the proper consistency. After all theingredients have been thoroughly mixed the composition is strainedthrough a fine sieve to render it perfectly smooth and consistent.

Care should be exercised in mixing the ingredients in order to obtain agood body, because the white lead varies in quality, and in consequenceof this water sometimes shows itself after the application of the paintto the surface of the material or substance. To test its body, dip apaint-brush into the composition while still in the vat and apply it tothe surface of the material or substance. A

workman of ordinary skill will be able to detect whether there is toomuch water. When water shows itself on the surface, small extraquantities of white lead and linseed-oil should be added; but if nowater appears then the body of the paint may be left without furtheradditions.

My composition is white when made according to the above-mentionedinstructions; but when, for instance, a grey tint is required asufficient quantity of common black paint is added; or for a cream tintsufficient con1- mon yellow paint is added. The tints may be varied atpleasure according to fancy.

I do not confine myself to the quantity of composition above mentioned,as I may proportionately diminish or increase the quantities accordingto the amount required; nor do I confine myself to the exact quantity ofeach ingredient, as it may be altered more or less according to thequality.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

The herein-described composition of matter, consisting of white lead,linseed-oil, whiting, sulphate of lime alum, glue, driers, and water, insubstantially the proportions set forth.

JOHN SMITH.
